Josh Barnett would dominate this fight....I also would like to note that AA is not that good, Barnett would take AA out quickly as well.

I agree fully. Neither Andrei or Sylvia would come close to beating Barnett. People give both AA and Sylvia way too much credit. Sure, they're the best heavyweights in the UFC, but that's not saying much at all. Barnett would have 2 easy wins with these 2.
